noun (plural same or boxfishes)

We saw crabs, eels, batfish, unicornfish, pufferfish, boxfish, lionfish, squirrelfish, racoonfish, butterflyfish, parrotfish and angelfish, to name just a few.

Like its relative the puffer fish, the boxfish propels itself by waving its dorsal fin (on top of its body) and its anal fin (on the bottom), and it steers primarily with its pectoral fins and tail fin.

The marine boxfishes (Teleostei: Ostraciidae) are mostly shallow-water, tropical reef-dwelling fishes that have 2/3-3/4 of their bodies encased in rigid bony carapaces, which arc keeled with various protuberances.
